Work Great for Fermenting Vegetables

  • When an airlock bubbles, it simply means that the air pressure inside the bucket or carboy is sufficiently high to push up the little column of water and relieve the pressure.
  • If it fails to bubble, all it means is that the pressure within the fermenter isn’t high enough to make it do so. This can easily happen if the lid isn’t fully closed, or if the seal isn’t perfect.

A Must Have for Home Brewing

  • For those of you not very familiar with Airlocks, this is a device that is needed when brewing things like beer, wine, meads, etc.
  • You just fill with 1/2 or 1/3 water, pop on the cap, and plug it into your fermentation vessel.
  • The airlock will allow the gas from the fermentation to escape while keep air and contaminants out.
  • An airlock just *feels* more professional, and is reusable, and is far less susceptible to clogging.
  • High transparency airlock help you keep and eye on how your fermentation is progressing better than the traditional plastic 'cylinder shaped' air locks.
  • Tips: Use pipe cleaners for cleaning

  • Will this work on 20 liters plastic bucket?

Answer: It doesn`t matter how big or small your plastic bucket is.It matter with the hole you drill on the bucket. If you use the grommet,you drill a hole 3/8’’. If #6 stopper,drill a hole 1’’-1.28’’.

  • How to prevent the stopper slide out of the jug/carboy?

Answer: It will slide when the pressure in the carboy increases and the mouth of the glass bottle has water. Wipe off the water stains on the mouth of the jug before use.

Warm Tips:

  • 1.Only fill your airlocks with clean water.
  • 2.Clean and sanitize the airlock and plug before every use.

The air locks with this type of lid vent around the top of the air lock and out the bottom of the red cap. I have seen other reviews for similar ones where people were complaining about the caps not having holes in them. These do not need the holes in the top because they vent differently than the ones with clear caps. 2 of mine had very small holes in the bottom of the water reservoirs and would not hold water. But after a quick chat with the seller I had a replacement in a few days. I would recommend these air locks and the seller had great and quick customer support. The only thing I have noticed is the description and photos say to drill a 3/8" hole for the black rubber grommets. This is wrong, the inside diameter of the grommets is 3/8 for the air lock to slide in. You need to drill a 12mm hole in whatever lid you are using to fit the grommet properly.

A 3/8" hole is way too small and the grommet barely fits.A 7/16" hole let's the tip of the airlock wedge in, but not go all the way through.A half inch hole is the correct size for letting the stem of the airlock pass through.Also, don't forget to use a little bit of keg lube. Keg lube is silicone based, so it's better to use that then something that's petroleum based like petroleum jelly.Anyway, the airlocks are great, but minus one star for poor information. The seller should know better.
